ADJUSTABLE SUPPORT FOR ELECTRIC WIRES.

SPECIFICATION forming part of Letters Patent No. 453,036, dated May 26,1891. Application filed February 18, 1891. Serial No. 381,838. (Nomodel.)

To all whom it may concern.-

Be it known that I, THOMAS H. BRADY, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inAdjustable Bracket-Arms forSupporting Electric \Vires, of which thefollowing is a specification.

My invention relates to improvements in adjustable bracket-arms forsupporting electric wires 5 and the object of my improvement is to adaptthe bracket for use as a right or left hand bracket, a hanging orstanding bracket, and in various places without the necessity for makingspecial bracket-s for different uses.

In the accompanying drawings, Figure 1 is a plan view of my bracket withthe bracketarm in full lines as extending to one side and with two otherpositions for said arm indicated by broken lines. Fig. 2 is a front viewof the same with one position for the bracket-arm indicated by brokenlines, and Fig. 3 is a side elevation of the same with the bracket-armand socket-piece arranged for use as a standing bracket.

A designates a bracket-arm, having at its outer end a pin a, preferabythreaded to receive and hold an ordinary insulator for the attachment ofelectric wires. The inner end of said bracket arm is provided with asquared shank b, that extends at right angles to the body of said arm,as shown. It also preferably has hollowed or recessed sides, as shown,for the end of the set-screwd to enter and furnish additional securityagainst accidental displacement.

C designatesthe socket-piece, having a base flange f, provided withscrew-holes to facilitate fastening in place by screws. The body of thesocket-piece has a square socket g extending through it in a directionparallel to that of said base, and a second socket h extending throughit at right angles to said base and socket J. The set-screw d, beforenamed, extends through the-body of the socket-piece at one side of saidsockets, so that its inner end enters both sockets at the point wherethey cross each other.

While I have illustrated the sockets as square in cross-section or endview and the shank as squared, it should be noticed that this is for thepurpose of preventing the arm from turning within the socket, and aspline and grooves or other known equivalent form to prevent one partfrom turning within another may be employed for said square form andwill be considered as an equivalent therefor.

When the bracket is to be used on a vertical wall, the socket-piece issecured with its base resting against the side of the building or othervertical support near the side, edge, or corner and the bracket-arminserted therein. If near the right-hand edge of said wall, forinstance, as indicated by the edge loin Fig. 2, the shank of thebracket-arm may be placed in the socket g, with the arm projectingbeyond said edge and side of the building, and if the bracket should beplaced near the opposite edge the arm would be put into the socketprojecting in the opposite direction, as indicated in Figs. 1 and 2 bybroken lines. If the bracket is to be placed near the middle of the sideof the building, then the arm may be placed in the socket so as to standat right angles to said side and base of the bracket, as also indicatedby broken lines in Fig. 1. If desired to fasten the base-plate on thetopof the'roof or other top surface or on the under side of a horizontalsurface, as the under side of a cornice, the arm may be placed in thesocket h, as shown in Fig. 3. In each case after the arm is placed inthe socket-piece the set-screw will be tightened to secure said arm inplace.

I claim as my invention 1. A bracket for supporting wires, consisting ofa socket-piece having a base to facilitate fastening in place, a socketextending in a direction parallel to said base, and a second socketextending substantially at right angles to said base, and a bracket-armhaving a pin at its outer end for holding an insulator, a shank to fitsaid socket at its op- 9 posite end, and an angular body between saidpin and shank, substantially as described, and for the purposespecified.

2. A bracket for supporting wires, consisting of a socket-piece and arm,the shank and socket of which have a form designed to prevent turningand adapting the shank to be inserted and held in position with thebracket-arm extending in different directions from said socket,substantially as described, and for the purpose specified.
